Closed PC PSU and Case

[Skellionz]

Why im helping out my friend i dont know because he is a git

but his pc is falling apart and i said id ask about for these things as he is poor and sad.

need at least a 550w (not some no brand thing that might break in a week) psu as his gpu needs that mimimum. and some kind of cheap case that has good airflow in it (fans a plus)

doesnt really want to pay any more than around 50 quid but also has a really good condition speccy cart of jetpac these are worth a fair bit if anyone is interested in it!

hi this might help

thanks for the post, but the psu is not powerful enough

A Coolermaster claimed to have 460W has 460W. A standard/cheap ATX PSU rated 550W/600W has great chances to have the same effective power of the above mentioned Coolermaster

Price is good, too.

A psu pushed above it's max is likely to die sooner than usual(even a good make) And make the system unstable. I know this from experience, and if u look I clearly stated what I wanted what power and why. I don't want a cheap no brand psu

whats going to go in this gpu/cpu

Can you post his PC specs? Since he is on a budget it wouldnt be a bad idea to work out his exact requirements if only for reasons of getting a second opinion. It could be he needs a bit less than you think. 550W is a fair bit of juice for most PCs with a single graphics card and not all cards suck beastly amounts of 200Watts + like some.

 

[Witcher1979]

Most GPUs today need at least 500w on any machine. My GPU states on the box:

500 watt or greater power supply with two 75w 6-pin PCI express power. I of course run 550w anyway.

Also Skellionz knows his stuff, if he says it needs 550w, I believe him

Cheers

Thats fair Jimbo. I just prefere to be sure in situations like this. It'd be a shame if he could have gotten away with something of better quality but winds up having to settle for something less than ideal just because of a miscalculation on power requirements

...Saying that though, allowing for 100W headroom even 550w may be squeezing it for most relatively modern systems. Processor and graphics are the main things to consider. My HD3850 states 450w minimum, relatively aging now but still a decent card for most modern games provided you're not after maxed out graphics.

I'm really curious whats in his PC now...

 

[Skellionz]

thanks jimbo as i sold my friend the pc i know exactly what power requirements it needs

Well tbh not that I don't appreciate the comments but rather than people saying they have what I'm asking for I'm being questioned by people thinking I don't know what I want.

I am after what I posted for and that is all. could any responses be limited to offers from now on, cheers guys

As far as I know, people are only sharing their knowledge and trying to give you suggestions.

Take a look here: http://www.tomshardware.com/reviews/~

Unfortunately, now another very important factor comes into play: the current. At these high values, many older power supplies fail when a new high-end graphics card is installed. Not all 500 watts are created equal, especially when it comes to cheap power supplies. Since many components are powered on the 12 V line, the power supply also needs sufficient current (amperage, A).

Let’s take the Radeon HD 4870 as an example. AMD states “500 watt power supply” as a requirement on the packaging. According to the actual measurements, though, the graphics card doesn’t need more than 150 watts even under full load. Now we’ll calculate in 150 watts for the CPU, motherboard and drives, 300 watts should be enough. If we assume from this a 300 watt load on the 12 V line, this means 25 A is required for this rail.

What you have to consider, in my opinion, is the Amperage:

With current brand name power supplies, things are different: pretty much every 500-watt brand name power supply will provide 25 A on the 12 V line. Even older brand name power supplies with fewer watts achieve the required targets.

And please note that a 550W ATX Power Supply of true good quality costs a lot, while you can have the same quality/brand for a lower price (less watts, but enough Amperage) and still be okay. Efficiency plays an important role as well if we want to estimate the *power* of such products, but Amperage is what really makes the difference.

Since you stated to have a limited budget, taking this into consideration is, always IMHO, very important.

jesus...i may as well talk to myself

Similar to what i was going to say..

theres always room for more wattage but i dont think much of anything can actually use up 800W with plenty of amps (above avarage but non crazy system),
having said that i do have a 1000W psu in my case, But i payed very little for it a number of years ago, and its never been a problem. And i hevily overclock.
Infact i payed less for that than a 500w psu would have costed me at the time. so Cheaper psu's really arent bad either.

just take in to account how many rails it has how many Amps each can supply, and what your system is going to be using.

p.s

stating that you need 500w for a gfx card may be the norm for manufacturers but its the amps not the wattage that should concern you.

Please can we keep this thread on-topic. It's a Wanted thread for a 550W+ ATX PSU, not an exercise in discussing the complexities of PSUs in general.

:thanks:

900W Tagan here. In perfect working order with only has seen about 3 months use. It has a switch called TURBO which makes it a Single Railed PSU which is highly recommended. Without TURBO enabled, it becomes a multi-railed PSU. It is not a Modular PSU btw & the Model number is TG900-U33 if you want to check out the specification.

As AmiBay rules suggest, please see PM for price.

 

[Skellionz]

Thanks for your offer but far bigger than i require

 

[Captain_Hat]

Don't think we've got a PSU that fits your requirements behind the repair bench at the moment (biggest I've found is a 400W) but we may have a case you can nab off us for not much. How big do you need, and do you mind very much if it has branding on it (i.e. "Dell" etc) as long as it's an ATX box?

 

[Skellionz]

I shall get back to you on that one!
