Recommended power supply unit?

hazardised · May 3, 2014

Hello! I'm making a gaming pc and don't know if the power supply I picked is enough. Here are the parts:-
Msi Z87-G43 mobo http://www.amazon.co.uk/MSI-Z87-G43-Motherboard-USB3-0-LGA1150/dp/B00CXOMGGW/ref=sr_1_1?ie=UTF8&qid=1398668228&sr=8-1&keywords=msi+z87-g43
I5 4570 http://www.amazon.co.uk/Intel-Graphics-BX80646I54570-Generation-Technology/dp/B00CV3E3WK/ref=sr_1_4?ie=UTF8&qid=1398269975&sr=8-4&keywords=I5
8gb ddr3 1600mhz ram http://www.amazon.co.uk/HyperX-Series-1600-Gaming-Memory/dp/B0057Q4ADU/ref=sr_1_sc_1?s=computers&ie=UTF8&qid=1398930678&sr=1-1-spell&keywords=Hypervx+blu
R9 280 http://www.falconcomputers.co.uk/xfx/r9-280-black-edition-3gb-amd-pci-express-graphics-card---with-amd-never-settle-3x-free-games-gold-voucher.html
And two 7200 rpm HDD's of 300gb

The power supply I would like is http://www.amazon.co.uk/EVGA-500B-BRONZE-Power-Supply/dp/B00DZ6R9GE/ref=sr_1_1?ie=UTF8&qid=1398278558&sr=8-1&keywords=500b

Is it enough? Thanks

id like to say that you should get a 650W to be on the safe side. It will allow for any future upgrades you may have. look into seasonic or xfx (which is made by seasonic) for an amazing modular PSU.

Power Supply: XFX ProSeries 750W 80+ Gold Certified Fully-Modular ATX Power Supply ($99.99 @ NCIX US)

this one is 750 watts but is the same price as a 650 seasonic psu. it is also a better quality psu being more efficient with the 80+ gold certification.

Edit just noticed youre from the UK? that would make the psu i suggested a bit too pricy at 96 pounds. however i still suggest you look for one from the two brands i suggested. or if the corsair hx series is available to you, they are good as well.

A Radeon R9-280 needs at least 30 amps on the 12v rail and a 550 watt power supply.

The 12v rail is the key here not the overall wattage.

The EVGA 500B has 40 AMPS ON THE 12V RAIL AND 2 - 6+2 PCIE Power connections , and is sufficient to run your specs.

Nice review on 500B ^

If you can stretch you budget this is a SEASONIC made power supply with 45 amps on the 12v rail.

of course you can take a seasonic / xfx psu ..but often they are more expensive

It should work, but just to be a little bit safe i'd go for 550w. XFX has a good 550W bronze model.

schau314 · May 3, 2014

I think the evga is fine, but the xfx is also good. Id take the cheapest that is still effective and efficient of those that is around 500 watts. You dont need any more, 500 is plenty.

bob hays · May 3, 2014

You do not need 750w, thats way overkill. The fastest single gpu doesn't need that much.

badboyrog2 · May 3, 2014

you need a minimum of 450W psu...so i always add 200W more to be safe, so 650W psu should be good enough
depending of the price...sometime you pay only 15 $ more for 100W more , so it will be futur proof if you add an other gpu in CROSSFIRE

bob hays · May 3, 2014

200w is A LOT of head room. Yes 750 is good for xfire so if OP is gonna do that then yes go for it, but if not, then don't

''200w is A LOT of head room. Yes 750 is good for xfire so if OP is gonna do that then yes go for it, but if not, then don't ''

actually i work on a client s computer who tought like you ... he have only 100W loose and now his pc shutdown randomly
so i replace the psu for a 200W more and now work like a hell

badboyrog2 :

That was probably a bad psu, or he made some upgrades that took a lot more power because like i said, 100w is a lot of headroom so even the degradation wouldn't cause it to lose that much (depending on what wattage it is, but assuming an average 500, thats 20%).

schau314 · May 3, 2014

Regardless if a 300 watt crap psu can supply 100 watts on an hp with that quality for many years, I think that 200 for headroom is not good. You want to have efficiency at idle also.
