Hi, I’m planning to upgrade my PC part by part so looking for advice from someone who have been using PSUs over 700w(with only home inverter/with home inverter and separate UPS for PC). I’m looking to buy a PSU around 750w. At present, I have a ‘Livguard Sine Wave Inverter - LGS1700’. Currently, and in the future, PSU will be the component with the highest wattage that I will be using during power cut. I have 2 TVs, BLDC fans, and possibly a sound system that will be under 200w in the future. Right now, I’m using a generic SMPS from Zebronics with APC 600VA UPS and home inverter. I plan to upgrade components gradually, except for the CPU, motherboard, and RAM, which I will purchase all at once(in future. Used/New).
If I upgrade my PSU to a 750w gold-rated unit, I will also need to upgrade my computer UPS so I have done a lot of research on whether we can manage the “load switch time“ of Inverter
“load switch time“ of Inverter in Unregulated mode - probably between 30 and 50ms or oven higher
“load switch time“ of Inverter in REGULATED mode - 15ms-20ms(Couldn’t confirm it’s exact value for above mentioned model)
To manage that timing we have to invest in a UPS. But, I don’t want to spend 10-15k on a UPS if possible. While researching, I found that power supplies come with something called ‘hold-up time’. Regular/Standard PSUs don’t have a hold-up time around 20ms. But higher-end models like the XPG Core Reactor 750 W, Corsair RM750x Shift and MSI MAG A750GL do have a hold-up time around or over 20ms(hold-up time - Will look into/confirm which one to buy at the time of buying).
I’m curious to know if anyone with these higher-end PSU models uses a home inverter along with a separate UPS for their PC, or if they use their PC with only home inverter. If it works well, I would prefer to invest more on power supply rather than on UPS(which may not last as long as the PSUs).
