Is this a good enough PSU?

[P3dro]

Hi, I built myself a new desktop about a month ago and I used my 2-3 years old Corsair GS700 in the rig. Yesterday it started burning out so I turned off my computer and I am looking for a new PSU. Since I used up my budget to build the desktop, I don't want to spend more than £100 on a new PSU. I found the Thermaltake 850W Toughpower Grand RGB for £95 and was wondering if it is a good enough PSU for my system (https://pcpartpicker.com/list/pgGytg) or if there are any better alternatives? The alternatives can be cheaper or slightly more costly if it is worth it  Also do I need 750W or 850W? I was lookign at 850W just in case I want to go dual GPU in the future.

Thank you for any advice

Yeah go for it I use it in my current setup. I just turn off the RGB because it gets annoying when I sleep. And 750W would be more then good

You could probably stand to go down some wattage. Even with dual GPU, what's your CPU? If you've got something like an overclocked i7, and 2 modern graphics cards in SLI, you still probs need less than 700W, so a 700W PSU would be a good place to start

850w will be good for dual gpu in the future for a second 1080, that card is 270w according to zotac, so lets say 600w for two cards with a light extra overclock on them

gives you plenty of room for the rest of the system and the i5

about 100w to spare which is what you want for a decent psu to avoid excessive heat and output loss

nah, those zotac 1080's are 270w a piece and require dual 8 pins

if they were FE stock 1080's then theyre only 180w, so even a 550w PSU could do two of them + the rest of the system, but not those zotac cards

Unless the CPU is a Ryzen chip, then i would go a tad higher.

but this is fine

Yeah it's fine.  Its not top tier but it's not a fire hazard either.

The 1080 is a 180W card. The Zotac claims 230W, presumably for marketing, not for the actual power draw. 

Even assuming that, 450W is plenty. The Toughpower has a high fan RPM, even at fairly low loads. If you want a loud PSU, you might as well go all the way and get the G3 or Prime Gold. 

If you want a quiet and well performing PSU, there's the Straight Power 11 450W, Whisper M 450W, RM550x 2018 and RM550x

You do NOT need a unit that outputs more than 550W! A GTX 1080, with OC, uses 250W if you really bleed the heart out of the thing. An i5 8400 uses maybe 75W.

 

A Corsair TX550M would be PLENTY for your system. A Seasonic Focus Plus Gold, Bitfenix Whisper/Formula Gold, EVGA G2/G3, Antec HCG Gold - these would be suitable alternatives.

^^^ I'm running a 980 Ti and R7 2700X just fine off a 550W PSU (EVGA G3), you only need more if you go for SLI.

Would the EVGA G2 550 be good enough for the current system? Don't think I will want to overclock really and if I decide to go for SLI I would just upgrade the PSU

Not good for £83. My recommendations are above.

Yes, it would be fine.
