I'm putting together some old LGA775 Core2Duo PCs to use as slave PCs in a sim network setup. Depending on the graphics card that I use, from a more efficient GTX750 to an older power hungry GTX480 (yes I know it also depends on the amperage on the 12V rail), eXtreme Power Supply Calculator gives me the following wattage ranges for PSUs:

E8500 ~3.8GHz (OC) 348W - 590W

E8400 3GHz 318W - 560W

So I'm looking for PSUs rated 400W - 650W. Any suggestions for budget PSUs under £50?

Rosewill is a decent budget PSU

 

But I prefer brands like corsair, Seasonic etc

I currently have a Corsair TX series PSU in my main PC, I'd heard about the CX series but also come across mixed opinions. I'd prefer something a little cheaper. Would Seasonic be your #2 manufacturer to consider? What bout CiT PSUs?

Try this: (50 or 40 after MIR)

Perhaps I should have asked are there any brands to avoid at under £50?

50 in whatever currency isn't much to work with if you want quality.... 555 reviews on newegg 4/5 stars is really good for 50 usd IMHO.

OK let me update this thread. I'm planning to use my current Corsair TX850 850W PSU in my new i7-4790K Haswell build. Now I'm after either:

 

Reliable PSU for non overclocked E8400 + GTX480 build

600W - 650W (Nvidia recommends 600W PSU min for GTX480)

80+ Bronze min

Doesn't have to be Haswell compatible

Under £50

 

Or

 

A a good quality PSU for overclocked Q9650 + GTX480 build

750W

80+ Bronze min

Doesn't have to be Haswell compatible

Under £80

Any suggestions for a 550W - 650W PSU (available in the UK) for around £50 better than a Corsair CX600? Won't be used for overclocking and doesn't have to be Haswell compatible.

Well I still want to do this project! The idea is an after-school club for kids to try flightsim. I'm setting my sites on GTX750ti cards (or GTX750 if the power requirements are much less). For GTX750 / 750Ti I've seen minimum recommendations from various manufacturers of:

300 to 400W

Total on 12V rails = 42A

From PC forums I've seen users suggest:

300W

Total on 12V rails = 20A

 

The PCs I'm using are old workstations and have the following PSU voltages:

#1 PSU = Dell L305P-01

305W

12V1 = 18A

12V2 = 18A

#2 PSU = FSP ATX-350PNF

350W

12V1 = 18A

12V2 = 16A

#3 PSU = HP PC6015

365W

12V = 12A

12Vcpu = 14.5A (Not sure if "12Vcpu" literally means for the CPU only???)

 

Q1) Could I run GTX750 / 750Ti cards with these PSUs?  Any thoughts are particularly welcome from those that have tried these cards with a 300W PSU.

Q2) Could I run any of these cards in particular:

# GTX750Ti

KFA2 GTX750Ti OC Slim 2GB

MSI N750Ti-2GD5TLP

# GTX750

KFA2 GTX750 OC Slim 2GB

Or your favourite single slot GTX750Ti / 750?

KFA2 GTX750Ti OC Slim 2GB

 

Requires... Minimum 400W or greater system power supply (with a minimum 12V current rating of 42A)

 

 

MSI N750Ti-2GD5TLP

 

Requires... Should be close to the above and below.

 

 

KFA2 GTX750 OC Slim 2GB

 

Requires... Minimum 400W or greater system power supply (with a minimum 12V current rating of 42A)

 

The requirements are there in your links. I wouldn't skimp on them if I were you. Anyone suggesting less than the recommended amps on the 12 volt rail, or rails, or lower wattage than recommended should be ignored.

 

It is true that the graphics cards also obtain a fair amount of power from the PCIe slot itself, but even so, I wouldn't recommend less than the requirements the manufacturer recommends, the manufacturers may be on the safe side, but they aren't stupid, they quote these requirements for a reason. Presumably you want stable systems. 

 

Given that your PSU's, which appear to be multi rail, have lower than the required total amperage... no they aren't suitable.

 

I'm sorry to say, that if you can't afford to do it, you can't afford to do it. 

 

If you'd like to spend a bit of money... Corsair VS550, 42 amps 550 watts. 37 quid. 3 year warranty!

The terms "budget" and "PSU" should not, in my opinion, be used in the same sentence.  Cheap PSU's fail and when, not if, they do they can fry a motherboard or anything else powered by the PSU.  Just my two cents, take it for what it is worth.

Agree totally, the most important component in the PC.

 

Why I suggested a quality make with a hefty warranty.

IIRC the 750s are notable because they pull all of their power from the PCIe slot - they do not require a 6 or 8 pin PCIe power connector. Max TDP of a 750 is 100W.

 

Cheers!

True for the reference design yes. Some of the non reference Ti cards require a 6 pin PCIe. Not sure about the cards the OP linked to.

 

Regardless, I still wouldn't ignore the manufacturers power requirements.
