Hello, I'm a complete power supply noob. I mean that in the sense of whats the best bang for the buck on the market not really in terms of knowledge about psu. Anyway I'm upgrading my rig to a gtx 770 (non-reference design) and I need a new power supply. So nvidia says minimum 600 watts but It's good to go over the minimum by 50-100 watts I've been told. So this is my current rig http://uk.pcpartpicker.com/user/Matthew12106/saved/NQMTwP
I do have a 8350 so I may need to go a good bit over but nothing seems like it should take too much power. Also I may be upgrading to add an ssd but they only use a couple watts. Anyway here is what I'm looking for if you know anything good
650-700 Watts
Black sleeved cables
Semi-modular would be really nice
80 plus bronze minimum
I'm really looking for something thats good price:preformance something around 50-60 british pounds ( I know most of you are american so... yeah).
I'm powering my GTX 770 Classified with an OC of 1293 on the Core and 8000 on the Memory and a 4670k at 1.2v OC to 4.5ghz using a Corsair RM650w. and for the record i have never seen this PSU fan spin EVER. you'll be fine.
I'll take your word for it, I hope you're right but I don't think my power supply is the most 'high end' so it might not be able to cope with being strained maybe I should atleast get a 600 or 650 watt one???
but what if it gets too strained and dies because it's not the most high end system and if its being pushed to near it's limits it could go boom and take a couple of components with it do you not think i should atleaat get a 600 or 650 watt you know just to be safe
you can run two 770s in SLI in a rig with a 650 watt power supply. Your XFX PSU is 80 plus bronze. It will handle your system fine. I am a fan of not spending money if it isn't needed. If you feel like spending money, then go ahead and buy a new PSU. More watts is not going to give you moar frames, and most computers don't use more than 400 watts under load.
The Seasonic S12II of the the XFX is a rebrand of is a solid unit its well designed and all the components are high quality, with a 770 you system is going to be somewhere around 440W assuming you have nothing other than what is listed on the partpicker list and a couple of case fans even then an extra HDD or 2 isnt going to add much which is about 100W bellow the rated capacity
Though even if the unit did fail it would more than likely do so gracefully, this isnt a bottom of the barrel unit it actually has functioning protection circuits and significantly higher quality capacitors among other things which the lack of in the really crappy units is generally the cause of damage to other components and or fires on PSU failure
It is worth noting the 'minimum' values AMD and Nvidia list are to cover their own arse in the event someone with a unit which cannot provide its rated power buys a card which is then damaged when the unit fails
its not. the CorsairRM series PSUs Fans are meant to spin when you are pulling a lot of wattage. During a Gaming load I know for a fact i'm not pulling more a lot if wattage cause the Fans don't spin.
For any SINGLE GPU configuration, a 650w PSU. is the best middle ground.
For any DUAL GPU Configuration, a 850w PSU is the best middle ground.
That's far too high lol. 650W is enough for two cards. 850W is enough for three, maybe four 0.0
Most high-end cards can run on 400-450. The extra 50-100 watts is just breathing room. 500W is absolutely fine for a single power-hungry GPU, with multiple HDDs, fans, whatever.
Not Really, 650w would be enough for two Nvidia Cards cause they don't pull much power but not AMD Cards. you wouldn't consider putting 2 R9-290x's or 2 R9-280x's with a 650w PSU, i mention 650w being the middle ground also taking into consideration if a person has multiple fans, an AIO water cooler, a couple hard drives. and an overclock on multiple components and if they wish to add extra components in the future like RAM, more hard drives, more fans, shit even a custom watercooling setup for a single GPU Config a 650w PSU they'll be more than fine.
Couple of R9 280x cards on a good 650W is absolutely fine. R9 290s, it's probably possible.
I'd say 500-550W, for a single card, is more than enough, including the things you've listed. An AIO is just a couple of fans and a pump. Very low wattage.
Agree, I run 2x R9 290x off an RM850 w/ 4790k, 4x hard drives, MPOWER Mobo, nhd15, etc etc. I've never once seen my power supply fan ever turn on. YOu should be ok.
