When will power supply prices drop?
Checked onNo one can give a date, and they are holding steady: the same 392 power supplies on Newegg cost about the same in total as on Sep 29, 2026.
What to do depends on how soon you need one.
What to do now
You need one this week
Buy now. Waiting has no measured payoff, and the price list shows the cheapest power supply of each kind.
An upgrade that can wait
Decide the price you would pay, then watch the 7- and 30-day moves. A product at the lowest price we have recorded for it says so on the list.
A new build
Price the whole build. The power supply is one part, and a cheaper choice elsewhere can cover a rise here.
What retail prices actually did
Of the same 362 products listed on Aug 3, 2026 and Oct 31, 2026, 106 cost more, 97 cost less and 159 were unchanged. Bought together, they cost 0.6% less on Oct 31, 2026.
This comparison uses the same products at both dates. It does not attribute every dollar of a shop price to a manufacturer's costs.

What would show Power supply prices easing?
A fall among the same products across several collection dates would show an actual retail change. More listed products at lower prices would broaden that evidence. A factory outlook alone does not give a date when a particular listing gets cheaper.
Use the retail chart to compare the dates, and the current price list to compare the exact part and its alternatives.
Why we give no date
We wrote a buy-or-wait rule and tested it on 1,252 past decisions across 11 factory price indexes, each using only the index months up to its own date, as BLS publishes them today (later revisions included). At three months, 29 of its 48 calls to wait were followed by a higher index: wrong 60.4% of the time. A date from a rule like that would mislead you, so this page gives the evidence instead.

The BLS series is other electronic component manufacturing (PPI), not the retail price of a power supply. Its match to this category is weak. Monthly manufacturing-index table.
