Stuck with a quality brand, that hit the 80+ gold level of specification. 7 year warranty isnt quite as much as some of the others however for the price it is just what I need. Happy to recommend.

Grunty

Max Output Power: 850W

Heaps of power running i5-14600K with 64GB RAM. So much headroom for overclocking and cranking up VM’s to get the most out of the CPU. Really impressed with all the optional cables and nice bag they come in. Easy modular plug and play set up. Only shortfall was the lack of instructions which I needed more info for around the way to use the 2x 8-pin cpu pci-e to a mobo with 1x 8-pin & 1x 4-pin. Found out after Googling for ages that in addition to using the 8-pin to 8-pin, it was safe to also plug in the second 8-pin but split the EPS cable and plug into the 4-pin mobo while leaving the other half of it hanging!

It's okay, but a little noisy.

Max Output Power: 850W

For the price it's pretty good but there are some downsides. The fan is not particularly quiet and it doesn't have a zero fan mode. Also the PCIE connector/cable looks very untidy, with a glass paneled case it's a little unsightly plugged into the GPU; it would have been nice if at least one of the PCIE connectors was a dedicated 8-pin rather a 6/8, it would look much tidier.
